- Possible smoke or loss of power.
- No noticeable symptom in some cases.
Possible causes

- Code entered incorrectly.
- Incompatible injector part.
- Control module replaced or reprogrammed without transferring injector codes.
Diagnosis and repair

- Compare it with the value stored in the module using a scan tool.
- Check that the injector part matches the one specified by the manufacturer.
- Program the correct code with a scan tool.
- Clear the code and road test.
